Does the distributor have vacuum advance?

: I made sure both the intake manifold

: If you can't find any external vacuum
: leaks, it could very well be due to an
: internal leak in one of the carbs,
: depending on exactly what carbs are
: fitted. For example, if they have
: throttle plate bypass valves, one could
: be sticking open and would give high
: idle and low vacuum. Some have the
: internal decell valve diaphragms,
: different flange spacers/gaskets etc.
: Can you drop the idle if you back the
: idle screws out all the way?
